Abstract: The structure of the title compound, {[Ag(C₁₀H₈N₂)]₂(SiF₆)·2H₂O·2C₂H₆O₂}_n, consists of two independent polymeric cationic chains containing Ag^I ions bridged by 4,4'-bipyridine ligands, hexafluorosilicate anions and cocrystallized ethylene glycol and water molecules. The Ag^I ion adopts a linear coordination geometry involving the N-donor ligands. A weak AgAg interaction is observed, resulting in the formation of a double-chain structure. The hexafluorosilicate anions and the solvent molecules are linked by O-HF, O-HO and C-HF hydrogen bonds to form a sheet-like structure parallel to the bc plane. The double {[Ag(4,4'-bpy)]⁺}_n chains are linked to this two-dimensional network by C-HO and C-HF hydrogen bonds, forming a three-dimensional network.
